Plasma based active flow control using dielectric barrier discharge plasma actuators was investigated to reattach the simulated separation flow on suction surface of turbine blade at low Reynolds numbers. The flow separation was induced on a curved plate installed in the test-section of a low-speed wind tunnel. Particle image velocimetry (PIV) was used to obtain two-dimensional velocity field measurements. The amplitude of input voltage for plasma actuator was changed from ±2.0 kV to ±2.8 kV. Large flow separation was moved closer to the curved plate by the flow control of the plasma actuator. The displacement thickness of the boundary layer near the trailing edge was reduced as much as 74.5 % at the maximum input voltage ±2.8 kV.
